Ah. There may be gotchas in there like EOL charaters and spaces that 
have to be 'just right'

I generally generate the encryption using the tools suggested.

e.g. echo 'mypassword' | openssl passwd -6 -stdin

echo 'raspberry' | openssl passwd -6 -stdin

Note you never get the same string twice...

Here is a userconf.txt with user pi password raspberry...

Ultimately that is a smoother way to access the Pi anyway
